Executive Summary & Key Takeaways

  • Chemical tanker compartments require statutory 3-year hydrostatic pressure tests and 1-year safety valve inspections under Petroleum and Explosives Safety Organisation (PESO) rules.
  • Drivers transporting hazardous cargo must complete specialized certified training every 3 years to maintain commercial licence endorsements.
  • Lapsed spark arrestor certificates or uncalibrated pressure gauges trigger immediate impoundment and cancellation of transport licenses.

PESO Statutory Clearances and Tank Approvals

Petroleum and hazardous chemical transportation operates under rigorous statutory control. Tankers must carry valid vehicle approvals, fabrication blueprint clearances, and approved route licenses.

Hydrostatic Pressure & Ultrasonic Thickness Tests

Tanker shells undergo periodic ultrasonic non-destructive testing to verify metal wall thickness against corrosive cargo wear. Hydrostatic pressure tests verify zero leakage under elevated operational atmospheres.

Driver 3-Day Dangerous Goods Training Endorsements

Standard heavy goods licences are insufficient for hazardous goods. Drivers must complete specialized training covering emergency response guides (TREMCARDS) and hazardous material spill mitigation.

Spark Arrestor & Pressure Relief Valve Calibration

Exhaust spark arrestors and emergency shut-off valves require documented periodic inspection to prevent ignition risks during discharge operations.
